TO ALL WHOM IT MAY CONCERTI:`

Be it known that I, KASSON FRAZER, of the city of Syracuse, in the county of Onondaga, and State of New York, have invented certain new and useful Improvements in Wedge-Buckles for Harness; .and I do hereby declare that the following is a full, clear, and exact description of the saine, reference being hadtoV the annexed drawings, which forni a part of this specification, wherein- Figure l represents a perspective view of the buckle, with haines-tug and a. trace in their places.

Figure 2, a perspective view ofthe wedge and tongue.

Figure 8, a longitudinal sectional view, showing the connection of the parts, and with the tongue inserted in the trace.

The letters used indicate corresponding parts whenever they occur.

All the parts may be made of malleable iron, wrought iron, steel, or other suitable metal for the purpose.

I make the buckle-frame A of proper size and shape, in the general form indicated by the drawings, and -with convenient loops, a b c, for various straps, and with a loop, d, for the hamesftug.

AtV the bottom of the buckle-frame A, and forming a part thereof, I make the bed-piece B, with as lot, s, for the guard of the tongue to play in, as hereinafter more particularly described. v i

As a part of the buckle-fran1e A, I make the cap e with supports, ff, on the sides, so arranged that such cap, in connection with the bed-piece B, will form an angular box, :v, Ythrough which the trace passes, and in which the wedge will operate, as hereinafter described.

.The cap e also has a slot or opening, g, into which the end of the tongue may play, and enables itto'move `to the left when the draught is applied. i Y

I rmake the wedge W in the general form, as indicated by the drawings, with bearing-surfaces, h h, on the under side thereof, long enough to avoid excessive local friction, which produces a wedge-form and action, and such wedge will be of proper size to readily move backwards and forwards on the bed-piece B.

The wedge W also has a transverse slot, z', to form an opening for the journal o of the tongue to operate in, and should be made with nibs, n n, to'clinch down upon said journal and keep it in place, and thus fasten the tongue to the wedge. Y

In the wedge W, I also make a hole, m, for the tongue to pass through, and with a stop, r, to keep-the tongue from dropping down too far, and Wholly falling out of the hole.

The tongue T is made with a journal, o, shank, p, and guard, q, and with a tongue proper, t, in ordinary form, substantially as shown in the drawings. Y

The. end of the guard g should be made in a T-shape, long enough transversely to cover the slot s in the bed-piece, and enable it to move backwards and forwards on the-under side of such bed-piece. I

The different parts being made as aforesaid, the tongue is put in place, and the nibs 1in, to close down upon the journal o, are clinched, substantially in the manner described, or the journal o may be held in any other ordinary way. In this manner the tongue T and wedge W are united by a joint, but a spring might be .used instead of the shank and journal, to serve the purpose of ajoint-in operating the tongue. I consider the vabove device, however, much preferable.

The wedge and tongue thus combined are then 4inserted in the angular box x of the frame A, with'the end A of the tongue t ready to play in the slot g, and the guard g in the slot s, and with theV bearing-surfaces h It of the wedge ready romove upon the bed-piece B. This bed-piece should be made as long as possible, so that the wedge may have a longer bearing thereon, which will also helpto render or move the trace more easily, and avoid excessive local copipressiony on the trace.

The edge of the bed-piece B, next to the loop d, should be brought up near enough to said loop to fairly allow the leather of the llames-tug H to pass through andiiil up the space, which being done, the wedge and tongue are prevented from dropping out by ghe guard q being confined to the slot c.

In preparing thc-buckle for use, the guard g'shuld of course be thus inserted before the haines-tug is applied.

The trace D being inserted at the small en d of the angular box z, (at the left, as shown in the drawings,)

and moved to theright, natlrailyshoves the Wedge forward, and as the end of the trace strikes the tongue proper, t, that is thrown backwards and downwards, and the passage of the trace is thus rendered comparatively free from obstruction. Then, when the trace is drawn back, the hole will-ordinarily catch the point of the tongue proper, t, or it may readily be done by pressing the guard g. v

As soon as the tongue proper passes into one of the holes, g/ y, in the trace, the natural effect of drawing upon the trace in the proper direction, will be to bring the wedge and tongue fully within the angular box w, and a powerful compression then takes place upon the leather, proportioned in degree to the draught, by the combined inuenee of the cap'e, the bed-piece B, and the wedge W in resisting such draught.

What I claim as my invention, and desire to secure by Letters Patent, irs- 1. The wedge W, when made with the transverse slot z', holem, and stop r; the tongue V'.l, madeV with then4 journal o, shank p, and guard g, each substantially in the form and for the'purposes described.

2. And I also claim the same parts, in combination with each other, when connected by ajoint, and forming a wedge and tongue, substantially in the manner and for the purposes described.

3. I further claim the Wedge W and tongue T, when 'made' as aforesaid, in combination vwith the buckleframe A, having an angular box, x, as deseribed,'all operating in the manner and for the purposes substantially as above set forth.
